DRAFT DEVICE FOR AUTOIVIOBILE-FURNACES.

SPECIFICATION forming part of Letters Patent No. 733,354, dated July '7, 1903. Application led December 31, 1902. Serial No. 137,229. (No model.)

To all whom t may con/dern:

Be it known that I, FRED CHARLES CHEESE- WRIGHT, a citizen of the United States of America, residing in the city and county of Denver and State of Colorado, have invented certain newand useful Impi-o versants in Draft Devices for Automobile-Furnaces; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to automatic means for regulating and controlling the draft of automobile-boilers, my object being to prevent back draft, to increase the supply of air for draft purposes as the velocity of the vehicle increases, and dispense with the fan heretofore provided for obtaining the necessary draft.

My further object is to provide a device of this class which shall be simple in construction7 economical in cost, reliable, durable, and thoroughly efficient in operation; and to these ends the invention consists of the features, arrangements, and combinations hereinafter described and claimed, all of rhicheill be fully understood by reference tothe accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a side view of an automobile-boiler, thefeatures constituting my improvement being shown in section. Fig. 2 is an underneath view of the same. Fig. 3 is a top view in detail of the rotary device for regulating the induction or admission of air to the burner. Fig. 4 is a similar view of the rotary device for regulating the eduction or escape of the products of combustion. Figs. 5 and 6 are front and rear views, respectively, of the boiler, the upper portion of which is broken away.

The same reference characters indicate the same parts in all the views.

rLet the numeral 5 designate the sheet-metal casing of the.boile11 surrounding the watertube compartment 6. This casing is provided With a flue 7, leading downwardly from its upper portion for the escape of the products of combustion. The burner 8 is located below the water-tube compartment. Tubes 9 carry the exhaust-steam from the engine (not shown) and discharge it below the burner.

Beneath the tubes 9 is a perforated plate or grate 10, through which the air passes to the burner from the rotary induction device 12. This device 12 isA provided with a funnelshaped mouth and a depending blade or wing 13, arranged to keep the mouth of the device directed toward the wind or in the direction from which the wind blows. This device 12 is journaled on a vertical rod or spindle 1,4, located below the burner and provided with a brace 15. A bar12a extends transversely across the top of the rotary device, an opening 12c being formed in its central portion, through which the spindle 1/1 passes. The device 12 is provided with a short upwardlyprojecting iange 12, which fits closely in a circular opening formed in the bottom of thc casing below the burner. The rear extremity of the apparatus is provided with a similar rotary device, through which the products of combustion escape from the flue 7. The lower extremity of this flue 7 has a rearward horizontal extension 7a, and the flue communicates with the device 16 by way of an opening 7c. This device 16 is journaled on a vertical spindle 17, made fast in the walls of the flue portion 7, and for this purpose the device is provided with a horizontal bar 16a, having a central opening 16c to receive the spindle. To the lower rear extremity of the device 16 is attached a depending blade or wing 18, arranged to keep the discharge-opening of the device pointed in a direction opposite that from which the wind comes. Across the discharge-opening of the device 16 is located a transverse conduit 16d, open at both ends for the escape of the products of combustion.

Below the bottom of the flue part 7? there is an opening 19, connecting the chamber 2O below the burner with the device 16, whereby a portion of the air which enters the induction device 12 passes directly through the chamber 20 into the device 16 and across the opening 7c, whereby a suction is created in the flue 7 and the draft increased.

When the apparatus is in use, the air enters IOO mum rim-ubu- Planta, Motor vehiClG- i d the funnel-shaped mouth 12g of the device 12,

which is always pointed toward the wind by virtue of the arrangement of the wing 13. The dotted lines in Fig. 2 indicate positions of the parts 12 and 16 at right angles to the position shown in Fig. 1 and at right angles to the direction in which the vehicle is traveling. The air entering this mouth l2g passes upwardly through the perforated plate 10 and between the exhaust-tubes 9, where it is heated before passing to the burner, from which it passes upward through the fire-tube compartment 6. The products of combustion pass downwardly by way of the line 7, rearwardly through the flue part 7 a, thence downwardly through the opening 7c, and finally out through the conduit 16d to the atmosphere. In the meantime a portion of the air entering the device 12 passes directly through the chamber 2O to the device 16, creating a suction in the tube 7, whereby the direct draft is increased and back draft prf vented, as heretofore explained.y

Having thus described my invention, what I claim is- 1. An automobile-boiler provided with a movable induction device located below the burner and arranged to be automatically regulated by the wind whereby its mouth is kept pointed toward the wind regardless'of the direction of the vehicles travel.

2. The combination with an automobileboiler, of a rotary induction device arranged to direct the air to the burner and provided with means adapted to be acted on by the wind to keep the mouth of the device pointed toward the latter.
